write Chapter 1 Economic growth concept
This chapter has to provide an overview of economic growth theories and economic growth factors. It roots your research in economic theory (which is needed because the role of a doctoral dissertation is to progress economic knowledge – and it has to refer to those theories which you are going to progress. In your case, those are growth theories. So you have to present them.
In the second subchapter of this chapter you have to show what factors are (again based on literature) responsible for economic growth. One of those factors you will recognize is going to be higher education. This subchapter’s role is to link general economic theory to the particular field of your research. So it builds an opening for the rest of your thesis and chapter 2.
Chapter 2 will address how education impacts economic growth. This chapter is mostly ready it just needs some reorientation of what you have already written. More details follow in my comment boxes.
Please read it carefully and apply.
